Specific embodiment
The invention will be further described for embodiment shown in reference to the accompanying drawing:
Referring to figure 1, a kind of oil liquid Particulate Pollution detection device, flow cell 1, the connection circulation including straight tube-like
The inlet tube 2 of the first end in pond 1, the filtrate liquor pool 3 being arranged in below the second end of the flow cell 1 are arranged in the stream
What the first test point 41 led in pond 1, the second end outer end being arranged in outside the flow cell 1 were arranged close to the flow cell 1
The first detection unit of second test point 42, the particle concentration for detecting first test point 41 and diameter is used
In the second detection unit for the particulate matter composition for detecting second test point 42, and the connection first detection unit
With the photoelectric detective circuit 6 of the second detection unit.Specifically, second test point 42 is located in the flow cell 1
On mandrel extended line, after liquid leaves flow cell 1, since the effect of inertia can keep the liquid of a branch of concentration, then fall into down
In the filtrate liquor pool 3 of side, liquid does not have the blocking of flow cell 1 at this time, and the kind of its interior impurity can be detected using second detection unit
Class.
The photoelectric detective circuit 6 calculates the particulate matter from described first according to flow rate of liquid in the flow cell 1
Test point 41 is moved to the time T that second test point 42 needs, and the second detection unit is in the first detection unit
It is detected after detecting the time T of the particulate matter.At this time second detection unit detection the intracorporal particulate matter of liquid be
The intracorporal particulate matter of liquid of first detection position before time T.Concentration, diameter and the composition of the particulate matter can be determined as a result,.
Specifically, first detection unit includes continuous optical power laser 51, the first plus lens group 52 and photodetection
Device 53.
Continuous optical power laser issues one plus lens group 52 of laser alignment and laser is converged to the first test point 41, works as oil liquid
In particulate matter circulated pond 1 by inlet tube 2, stop and scatter a part of light by particulate matter when the first test point 41
Line, so that the light intensity for reaching photodetector 53 becomes smaller.The small-signal that photoelectric detective circuit 6 exports photodetector 53 into
Row amplification and processing, obtain a undersuing.The size of pulse amplitude and particulate matter is proportional.By to pulse
